Application filed September To all whom it may concern.

Be it known that 1. JOHN W. KnNnnrcIi, a citizen ot the United States, residing at Chicago, in the county of Cook and State of llliuois. have invented certain new and useful improvements in Tool-Cars, of which the following is a specification.

The object of my invention is to provide apparatus for driving screw spikes in railway ties.

More particularly my object is to provide a car carrying ap iiaratns by which a plurality of screw spikes may be driven siinnl taneously into the ties beneath the car.

These and other objects will be made apparent in the following specification and clain'is, when taken in connection with the accompanying drawings in which Figure l is a side elevation of a car embodying my invention. Fig. 2 is a top plan view of the same the root being removed. Fig. 3 is a cross section of the car taken on the line 3 of Fig. 1 looking in the direction of the arrow. Fig. l-

a sectional. view of a detail. Fig. 5 is a top plan view of the element designated as 75 in Fig. i. Fig. 6 is a bottom plan view of the opposed element designated as 72 in Fig. at. Fig. 7 is a top plan view of a car which is intended to be coupled to the main tool car for the purpose of supplying power thereto and also moving itover the track.

As is well known, the ordinary straight railroad spikes are usually driven by the blows of a hammer actuated manually. ()ne objection to the use of screw spikes is that a great deal of time and etllort is required to drive them manually. The wrenches by which the screw spikes are driven by hand usually require two men to operate them, and it is a long slow process to drive a single spike,-requiring several minutes. By my invention screw spikes can be driven with great rapidity by the application at power, and thus an obstacle to their use overcome.

In the particular form of my invention which I. have chosen to illustrate in the drawings a long car is provided having the center sill and the body bolsters is above the trucks. At one end of the car a floor 17 is provided above the center sill l5, and on this floor two compressed air tanks 21 are placed. These are supplied with compressed air from the steam-driven compressors 22, which are attached, respectively, to the external. side walls of the tanks 21. These air Specification of Letters Patent.

compressors 22 and therefore Above the car is the root on. the side posts 26. Under the root, on each side. the longitudinal compressed air supply pipes .27 extend the full length of the car from the respective tanks 2i, control valves being provided in each pipe. From the supply pipes 7 flexible branch pipes 27 extend to the pneumatic spike-driving tools, which will be described presently.

Attached to the upper side of the center sill 15 are the two long plates 29, having the cross section shown in Fig. or frames are bolted to the center sill, as shown. Riding on each frame plate 29, and supported thereby. are a plurality of pneumatic spikewlriving tools. one of which will now be described in detail.

The bed frame 30 has rollers 30 atits inner end, which rest upon the inner flange of the frame plate 2 The bed 30 also 31. which reaches ever beare of any well known type, need not be described in detail. supported by has an extension hind the flange and carries rollers 32 on the under side of said liange. The bed 30 also carries other rollers 3%, which rest upon the outernnistflange ot' the frame plate 29. This flange has rack teeth out on its under side. and a gear pinion 56 engages these rack teeth. This gear pinion 36 is carried at the end of the shaft 37, which is mounted in brackets 38 on the bed 30, and at the end of the shaft 37 is a hand wheel 3.) for rotating it. The bed 30 also carries a transverse sha 't- 4-], having a hand wheel it) atone end and gear pinion 42 at the other end. lhis gear pinion i1 engages a rack at?) on the under side of the overlying bed plate :'l-t.

' On the upper bed plate ell is mounted a pneumatic motor as, which is adapted to rotate the gear pinion at It bracket 4.7, standing on the bed plate l, carries a shaft with a gear whccl 14.8 which engages the said gear pinion it). This shaft also carries a bevel pinion it), which engages a bevel gear wheel on the vertical shaft 51. This shatt 51 has non-rotative engagement with the bevel gear wheel 50, but is free to slip vertically with relation thereto. A link has one end pivoted to the upper end of the standard '17. and its other end is pivoted to an intermediate point on the lever which has a counterweight at one extremity and at another point is pirotally connected to the upper end of the sliding shaft 51. A1

These plates its outer extremity this lever 53 has a handle 56 attached thereto by means of the link Near its lower end the sliding shaft 51 carries a sleeve 70, with a hand wheel 5'? thereon. This sleeve is rotatably mounted on the shaft 51, and hence may be employed to raise and lower the sliding shaft 51 or to direct the movements of the same. A stud 71 is screwed into the lower end of the shaft 51, and this has a head 7 2 with sector-shaped teeth '73 on its lower face. The shaft '76, which hangs directly below the shaft 51 and in line therewith, has a stud with a projecting flange 7 5 screwed in its upper end. The sleeve 69 screws on the lower end of the shaft 51, and has an inturned flange 68, which engages the flange 7 5. Sectorshaped teeth 7% project up from the flange head 75 and are adapted to engage the downwardly projecting teeth 73. The teeth 73 and 7% are slightly beveled, and the play afforded the flange '75 within the sleeve 69 is such that these teeth may or may not engage one another. The shaft 76 carries a socket 58 at its lower end, adapted to fit over the head of the screw spike 59.

he stem 63 projects through a hole 67 in the hand wheel 57. On its upper side the hole 68 is bounded by a split tapered threaded sleeve 66. The correspondingly threaded wing nut 65 engages the sleeve 66.

A small car, shown in Fig. 7, is provided to carry a steam generator for the air compressors 22, and also to carry a steam motor for moving the tool car. On a platform 80 stands a steam boiler 81. The fuel box 82 and the water tank 83 also stand on this platform. A steam supply pipe 8st leads from the boiler 81 and connects by a section of flexible tubing 85 to the branch pipes 86, which lead to the air compressors A valve 87 is provided in the steam pipe 84.

A reciprocating steam engine 88 stands on the floor 80, being supplied with steam through the valve 90 by means of the steam pipe 89. The crank shaft 91 of this engine carries a gear pinion 92, which engages a large gear wheel 93 on the countershaft 91-. This countershaft carries a sprocket wheel 95, from which a chain 96 transmits the power to a sprocket wheel 97 on the axle 98.

When in use the tool car shown in Fig. 1 and the auxiliary car shown in Fig. 7 are coupled together. By means of the engine 88 the auxiliary car acts as a motor car to move the tool car from one place to another as may be necessary. The steam generator 81 supplies steam through the pipe 81 to the steam cylinders of the air compressors 22, and these air compressors compress a supply of air in the tanks 21. Then when the tool car shown in Fig. 1 has been moved over a section of the track in which spikes are to be driven, the pneumatic tools emsill 15 are moved by ployed on the center positions required for operators to the exactdriving the spikes. Rotation of the hand wheel 39 moves the tools longitudinally, and then a transverse adjustment may be secured by means of the hand wheels 10. Through the driving connections that have been described the pneumatic tool 45 causes the sliding shaft 51 to rotate. Normally the counterweight 5st holds this shaft up, and at such time the flanged head 7 5 on the lower shaft 76 drops to the bottom of the sleeve (39, and thus the teeth 73 and M do not engage each other. But when it is desired to drive a spike 59, the shaft 51 is pulled down by means of the handle 56, causing the socket 58 to engage the head of the spike 59, and also causing the teeth 73 and 7 1 to interlock. When the spike is driven home, if the operator fails to disconnect the socket 58 therefrom, the stem 63 will strike upon the tie or the tie plate. This will prevent the shaft 51 from descending, and will thus cause the interlockingteeth 73 and H to separate slightly. For the reason that they are beveled, they will slip entirely apart the moment they are started apart. Thus the driving shaft 51 will be disconnected from the spike 59, and there will be no danger of loosening the spike in the hole in the tie.

After driving the spike the operator can quickly shift the machine by means of the hand wheels 39 and a0 to drive another spike. Thus, in a few minutes all the spikes can be driven under the entire length of the tool car. Then steam can be turned into the engine 88 on the auxiliary car, and the tool car can be moved by its own length to an adjoining section of the track, where the spikes can be driven in the same manner.

At is obvious that instead of transmitting the power by compressed air I could provide a single mechanical motor with shafts and belts to communicate the power therefrom to the several spike-driving tools. It is also obvious that the steam generator and other elements and apparatus mounted on the auxiliary car could, if preferred, be mounted on the main tool car. All these variations, and others, are comprehended within my invention in its broader aspect.

it may be desirable in certain cases to employ several spike driving tool cars coupled together in series and supplied with steam from a single boiler. For example, an ordinary locomotive could be substituted for the auxiliary car illustrated in Fig. 7 and this locomotive could perform the two functions of supplying steam to the air compressors on the tool cars and acting as a motor car to move the tool cars from place to place.
